Definitions

  • the invention relates to a closed hearth, a stove or a fireplace insert. It will find its application in particular in the manufacturers of domestic heating equipment.
  • the heating rate of the closed hearth, stove or chimney insert is completely controlled by the adjustment of the primary air intake, i.e. the air intended for direct combustion and which is admitted under the hearth. Under these conditions, the closed hearth, the stove or the chimney insert present an excellent calorific output and their operation is carried out in complete safety since there is no risk of projections of incandescent sparks outside. fireplace.
  • French patent FR-A-2,617,270 describes a closed hearth at high temperature having an air intake at the front door, and on all its other faces, a layer of significant thermal insulation in order to allow operation. at high temperature.
  • the main object of the present invention is to present a closed hearth or a stove or a fireplace insert which has a front glass door, specially designed to be self-cleaning.
  • the closed hearth, stove or chimney insert of the present invention has a particular construction to benefit from an improved heating efficiency with combustion conditions reducing the emission of polluting fumes.
  • the implementation of the present invention does not require fundamental transformations in the method of construction of closed fireplaces, stoves or chimney inserts, which allows it to remain economical and competitive.
  • FIG. 1 shows schematically in section a closed hearth equipped with a glass front door executed according to the present invention.
  • the present invention relates to a closed hearth, a stove or a fireplace insert. It mainly concerns manufacturers of heating equipment.
  • the invention relates to the operation of closed hearth heating appliances which have a glazed front door.
  • Such appliances offer many advantages over the traditional hearth fireplace. Indeed, its proper functioning is ensured and the closed hearth heating regime makes it possible to benefit from a high energy yield.
  • the spectacle of the flame being very sought after by the users, the manufacturers offer their equipment equipped with a glazed front door to combine the advantages of the closed hearth heating regime as well as the vision of the flame with in addition the presence of a security screen.
  • the best known technique consists in creating a whole series of orifices on the periphery of the glass through which a secondary air suction movement is created which results from the depression prevailing in the hearth of the fireplace. This technique has the disadvantage of being ineffective and of causing disturbances in combustion.
  • Some manufacturers also use a thermally insulated hearth to increase the combustion temperature, which has the effect of reducing polluting smoke emissions.
  • This efficient technique has the drawback, however, of bringing the combustion temperature within limits that are difficult to accept for the mechanical strength of the parts.
  • the infrared radiation is important and causes uncontrolled heating.
  • FIG. 1 shows schematically in sectional view the internal architecture of a closed hearth (1) or the like connected to a smoke evacuation duct.
  • the closed hearth has a front door (3) closing a hearth (4) where the combustion of a hearth (5) is maintained above an ashtray (6).
  • combustion takes the form of wooden logs (7) supported by a grate (8).
  • the door (3) is glazed to allow users to benefit from the vision of the flame (5).
  • the hearth (4) is surmounted by a drain (9) through which the fumes resulting from the combustion of the hearth (5) escape.
  • the admission of combustion air in the form of a supply of primary and secondary preheated air takes place in such a way that a rotating movement is created as shown by the arrows (10). in the hearth (4) of the closed hearth (1).
  • This combination of preheating and gyratory movement has a very beneficial influence on combustion and in particular makes it possible to reduce the emission of toxic fumes and to avoid blackening of the front door window (3).
  • the primary air intake this is achieved through the front door (3) which has for this purpose double glazing (11 and 12).
  • Primary air is admitted at the base of the front door (3) as shown by the arrow (13). Primary air circulates between the panes (11 and 12) where it is preheated. Then the air opens at the upper part of the front door (3) through a slot as shown diagrammatically under the reference (14) in FIG. 1.
  • the control of the primary air intake can for example be carried out by means a valve (15) located at the air inlet (13) in the front door (3).
  • the primary air which opens at the top of the glass door (3) is oriented so that the air circulation is done by descending along the interior face of the glazing (12) as shown schematically by the arrows (16 ) of Figure 1. This creates a continuous curtain of clean air that prevents blackening of the glazing.
  • the secondary air intake made in the upper rear part of the chimney insert combined with the primary air intake located in the upper part of the front door (3) with a downward movement creates the rotating movement (10 ) very favorable to combustion.
  • the rotating movement (10) creates a mixing of the fumes which avoids the production of unburnt products.
  • preheated combustion air makes it possible to increase the combustion temperature above 350 ° C. to improve the heating efficiency and reduce the emission of polluting fumes.
  • the rear deflector (23) prevents secondary air from being directed directly to the duct (2) smoke evacuation. Its role is to direct the secondary air flow down the hearth (4).
  • the front deflector (22) maintains the rotary movement (10) and prevents the vortex from being directed towards the smoke exhaust duct (2).
  • the baffles (24 and 25) slow down the circulation of smoke (26).
  • the baffles (24 and 25) will be removable so that they can be cleaned.
  • Another advantage of the secondary air intake at the upper rear part of the hearth is that the combustion fumes are enriched with oxygen in an area close to the exhaust duct, which reduces unburnt.
  • the closed hearth (1) will be equipped with an auxiliary starting air intake circuit, located at the base of the hearth at the ashtray (6) as shown schematically by the arrows (27) in Figure 1.
  • the fireplace outlet (1) is advantageously fitted with a probe measuring the temperature levels of the combustion fumes. Below a certain critical threshold, the user is invited to refuel the fireplace to maintain a minimum operating temperature.
